SUPPORT FOR ELECTRIC-RAILWAY WIRES.

SPECIFICATION formingpart of Letters Patent No. 398,489, dated February26, 1889.

Application filed September 19, 1888. Serial No. 285,768. (No modeld Toa?! 1/71 0/)? '1'/' 11/41 can earn Be it known that I, THOMAS ll. BRADY,a

Britain, in the county of Hartford and State of Connecticut, haveinvented certain new and useful Improvements in Poles and Brackets forSupporting \Vires for Electric Railways, of which the following isaspecification.

My invention relates to improvements in suspending the wires forelectric railways; and the objects of my improvement are to thewire-holder adjustable upon the bracketarm, and to improve the generalconstruction for the sake of economy in production and convenience insetting up the parts.

In the accompanying drawings, Figure l is a side elevation, partly inhorizontal section, of my pole and bracket-arm. Fig. 2 shows,respectively, a plan view and side view of the cap-iron. Fig. 3 shows aside view and front view of the truss-iron that is secured to saidcap-iron, and Fig. 4 shows inside elevation a slight modification in theend of the bracketarm.

A designates a pole to be set up on one side of the roadway, and B thecap-iron which is secured to the upper end thereof. The body of thiscap-iron is tubular, to be fitted to the upper end of the pole, and itis provided with a lateral lug, 5, containing two holes or mortiscs, 6,Fig. 2, and an upwardly-projecting lug, 7, having a semicirci'ilarrecess in its upper edge.

I form the bracket-arm C in the form 01' a truss, as shown. This trusscomposed of a the lower bar or tube, 8, truss-irons 9 1.0 11. 12

13, truss-wire 1i, and extension 15. The truss-iron has two hooks, 1 (5,upon its under side, which are hooked into the i'nortises (i of thecap-iron, while the body of the rod 8 en- I hold the bracket-arm tirmlyin position. The

it an ordinary wireho1der, 18, from which the The extension 15 slideswithin the tube 8 in the construction shown in Fig. 1, and is fastenedin place by the setscrew 1i), whereby it may be extended outward orinward to brin the wire-holder and wire in their proper position overthe track. After the extension is thus adjusted the extension-wire maybe attached, as shown, so lessen the number of poles employed, to make 1tcrs the recess in the upwardly-projecting lug 7 of the cap-iron. Theend truss-iron, 9, has

of said brace is fastened to the pole, so as to as to form acontinuation of the truss-wire 14 to substantially the end of thebracket-arm.

In Fig. substantially the same construction is shown, except that theextension 15 is adjusted within sockets 21 and 22, instead of within therod By my improvement it is only necessary to place the poles upon oneside of the track; the wire-holder may be adjusted to bring it centrallywith the track, and the parts are cheaply produced, easily put together,and are of substantial construction.

I claim as my invention 1. The herein-described support for the wires ofelectric railways, consisting of the pole A, the bracket-arm C, and theadjustable extension 15 at the outer end of said bracketarm,substantially as described, and for the purpose specified.

2. The bracket-arin C, consisting of a lower bar, truss-irons,truss-wire, and an extension at the outer end, and the extension-wire20, for forming a continuation of the truss-wire to near the outer endof said bracket-arm, substantially as described, and for the purposespecified.

3. The eombinat ion of the pole A, cap-iron 13, having lugs 5 and 7, thetruss titted to said cap-iron, and the brace 17, substantially asdescribed, and for the purpose specified.
